The working principle of the hydraulic machine:
1. The working principle of the hydraulic piston radial piston type hydraulic motor. When the pressure oil enters the bottom of the plunger in the cylinder through the window of the fixed oil distribution shaft 4, the plunger protrudes outwardly and tightly against the inner wall of the stator. There is an eccentricity between the stator and the cylinder. At the point where the plunger is in contact with the stator, the reaction of the stator to the plunger is.
2. Hydraulic force can be decomposed into two component forces. When the oil pressure acting on the bottom of the plunger is p, the plunger diameter is d, and the angle between the force and the force is X, the force generates a torque to the cylinder to rotate the cylinder. The cylinder body is further outputted by the end face of the drive shaft to output torque and speed.
